WASHING-MACHINE.

SPECIFICATION forming part of LettersPatent No. 730,952, dated June 16, 1903.

Application filed January 5,1903. Serial No. 137,973. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE EDWARD MUTH, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Washing-Machine, of which the following is a specification.

My invention is an improvement in reciprocating washing-machines, and relates especially to machines of that type in which the rubber is non-revoluble and the tub movable.

My improvements relate especially to the manner of mounting the tub on the base employed and to the means used for holding the rubber against rotation, at the same time allowing a slight vertical movement of the rubher.

I am aware that washing-machines have been constructed embodyingastationary rubber and revoluble tub and do not claim that idea broadly.

In the accompanying drawings, Figurel is a perspective view of my washer complete. Fig. 2 is a sectional view taken through the center of the tub, parts being shown in elevation. Fig. 3 is a plan view of the supporting-collar and springs attached thereto. Fig. 4 is a detail plan view of the casting on which the collar rests. Fig. 5 is a perspective detail view of the spider. Fig. 6 is a similar view of the collar. Fig. 7is a detail of the lockinglever.

In carrying out my improvement I employ a suitable chair-frame having the legs A, side pieces A, and back A AcastingB is formed, the ends of which are adapted to rest on opposite sides of the chair, and adjacent each end of the casting are laterally-projectinglugs B, which extend downward and are adapted to be bolted to the inner faces, of the side pieces. Midway its ends a cylindrical core B is formed on the casting, projecting above and below the portion bearing the lugs 13, and this core is perforated at 13 formed on it, and below the shoulderis formed an annular groove 13 which is also below the upper surface of what may be termed the arms B of the casting. At the ends of the arms are upwardly-projecting bifurcated lugs E the bifurcated portion forming a pair of cars at the outer end of each arm. A cylindrical collar 0 is formed, the collar being 'fit over the groove B and number to the ribs F A shoulder B is perforated at O, a shoulder being formed at O whereby the collar is adapted to fit over the shoulder B. The under face of the collar has a shallow annular groove adapted to The collar has arms C projecting on opposite sides, the arms being perforated at O and above the arms-are cut notches C in the collar.

Springs D have their outer ends turned in opposite directions and are hooked under one of the ears B and at their inner ends to the arms O their ends having hook members ongaging the perforations.

A spider E, having a straight horizontal upper face and an inwardly downwardly inclined lowerface, has a cylindrical perforated enlargement E, adapted to fit over the collar Oand on its lower face has downwardly-projecting lugs E adapted to fit into the notches C and prevent rotary movement of the'spider relative to the collar. At its ends the upper face of the spider is ofiset, being in a plane slightly above the central portion, and on each ofiset E is formed a spur E On the inside of the tub Fa metal plate F is bolted to the center of the bottom of the tub and has a vertical rod F extending from it. From the sides of the metal plate extend a plurality of radiating ribs F resting on the bottom of the tub, the ribs gradually increasing in height toward the sides of the tub.

The rubber comprises a wooden disk G, having a diameter nearly as great as that of the bottom of the tub, centrally perforated and carrying ribs G, correspondingin shape A metallic plate G2 is fastened to the upper side of the wooden disk, and this plate has a sleeve G which extends downward through the perforation in the disk and upward above the sides of the tub, the sleeve having a downwardly-open socket G running almost its entire length. A lever H, bifurcated at the end H and having a handle at H is pivoted at the bifur cated end to the upper endof the sleeve, and the'handle end, which is reduced adjacent the handle H rests in a hook H carried by a plate H secured to the back of the chairframe. In assembling these various parts antifriction-balls are placed in the groove B and the collar and springs secured in position.

The spider is then placed in position,

' against rotary motion, but can rise and fall with the splashing of the water and motion of the clothes below it, and by giving the tub a reciprocating motion by means of the handle F the clothes will be thoroughly rubbed between the ribs carried by the bottom of the tub and the disk. The washer will not only rub the clothes, but will throw the water through the clothes and wash them thoroughly.

Having thus fully described my invention,

what lclaim as new, and desire to secure by Letters Patent, is-

1, A washing-machine comprising a frame, a casting having a central perforated core and arms adapted to rest on the frame, bifurcated lugs at the ends ofsaid arms,downwardly-projecting brackets adapted to be secured to the frame, the casting being provided with an annular groove formed around the core and a shoulder formed on the upper portion of the core, a collar adapted to fit on the core and cover the groove,a tub-support carried bysaid collar, antifriction-balls in the groove, and springs secured at one end to the lugs at the ends of the arms and at their opposite end to the collar.

2. A washing-machine comprising a frame, a casting thereon having a central cylindrical core extending above and below the casting, an annular groove around said'core adapted to receive antifriction-balls, a collar fitting over said core, arms projectingfrom the sides of the collar, springs connected to said arms and to the casting, said collar being notched on opposite sides, a spider having spurs on its upper face and having lugs on its lower face adapted to fit into the notches formed in the collar, and a tub on the spider bearing on said spurs.

GEORGE EDWARD MUTH.
